Books on Patristics

What book(s) do you recommend on church history with emphasis on the church fathers? Would prefer something which is not biassed toward a given denomination or church, but an objective overview of the important personalities and their influence on the christian faith and culture. This meaning that I am really interested in their main dogmatic views and theological contributions. Even if this seems to be a very broad topic and field, could you recommend me the book(s) that were helpful for you and your understanding on this? I have not studied church history so far, and have a very basic knowledge, but I am becoming more and more interested about it and would like to study it in more detail. I also think, that this is very important for my general knowledge and also my faith. (In the community I have been raised, there was not so much accent on Church History in general).
